Dev_c++下解决编译winsock和pthread 的链接问题

在DEV-C++中编译含WINSOCK的代码总出现这样的问题
undefined reference to `inet_addr@4'
undefined reference to `gethostbyname@4'
undefined reference to `WSAGetLastError@0'
undefined reference to `inet_ntoa@4'
undefined reference to `WSAStartup@8'
undefined reference to `inet_ntoa@4'
undefined reference to `socket@12'
undefined reference to `htons@4'
undefined reference to `bind@12'
undefined reference to `listen@8'
undefined reference to `accept@12'
undefined reference to `recv@16'
undefined reference to `send@16'
undefined reference to `shutdown@8'
undefined reference to `closesocket@4'
undefined reference to `closesocket@4'
undefined reference to `WSACleanup@0'

编译器选项，连接器命令输入框中增加
-lwsock32

如果想编译多线程程序,在连接器命令输入框中输入
-lpthreadGC2
